3 Claims.

The present invention relates to a duster and has to do particularly with the formation of a metallic support or back therefor.

tofore in the past generally been made of wood.

The Wooden back or support therefor has assumed a number of different configurations.

Metal backed dusters have not been highly popular because of the expense of production, with 15. consequent high retail price, such expense being either due to the multiplicity of parts, expensive assembly, or the waste of material.

The object of the present invention is to provide a new and improved metal back for a duster.

A further object of the invention is to provide a new and improved form of duster.

A still further object of the invention is to provide a blank of adapted to be used duster or the like.

Another object of simplified structure unique design particularly for forming the back of a the invention is a new and for a duster or the like.

These objects, and such other objects as may hereinafter appear, construction, unique are obtained by the novel arrangement, and improved combination of elements illustrated in the accompanying drawing, showing one embodiment of the invention, and in which: 35. I Figure 1 is a plan view of the blank used in producing a cluster support or back hereinafter to be described;

Figure 2 is a plan view of the top of a duster made from the blank shown in Figure 1;

V Figure 3 is a front Figure 2; and

view of the device shown in Figure 4 is a transverse section on the line 4-4 of Figure 2.

Like reference characters are used to designate similar parts in the drawing and in the description of the invention which follows.

Reference will be had first to Figure 1. The

blank there shown includes a body comp-rising sections 10 and 11 divided one from the other by a plurality of dotted lines 12, 13 and 14,

which dotted lines are adapted to represent folds later to be made in the blank. Sections 10 and 11 form a horizontal crown sheet in the completed mop head. also around the sec Around the section 10 and tion 11 are complementally arranged tabs which are designated 15, 16, 17,

18, 19, 20, 21, 22, 23 and 2%.

Said tabs or extensions have apertures 25 therein to receive rivets for securing a strip of thrums 26 to the duster head, said thrums 26 being held together. by a fabric strip 27 in which there are stitches 28. From the blank shown in Figure 1, the device illustrated in Figure 2 is adapted to be manufactured. By folding the blank on the lines 12, 13 and 14, a Well or groove which is separated from 652. i the blanks l0 and 11 by the folds l2 and 14 is obtained. Between the sections 10 and 11, 12 and let space for the insertion of a socket is thus obtained.

The strip of thrums 26 is adapted to be riveted or otherwise secured through the strip thereof which is secured to the flanges 15, 16, 1'7, 18, 19, so? 20, 21, 22, 23, and 24, after said flanges are folded until normal to the top face of the sections 10 and 11, as is shown in Figure 3.

Thus a relatively simple blank is provided for the production of duster heads, and instead of 5:1: wasting a large amount of material to provide by direct cutting, a blank following the outline of the device shown in Figure 2, a more economical blank is provided, as is shown in Figure 1, the fold of the blank shown in said Figure 1 being a rela- 0:; tively simple and inexpensive operation. Such arrangement concurrently provides simplified means for securing the socket 30 upon the device by means of the bolt or machine screw 31 extension through the vertical walls of the trench be- 5;

tween sections 10 and 11.

I claim:

1. In combination, a mop having thrums, a handle, and a mop head comprising a single sheet of metal long in transverse dimension and short 100, in its front to back dimension, portions of the outer edges of said sheet of metal being turned down to form a rim to receive the thrums, and the central part of said sheet being sharply depressed to form a front to back handle receiving groove deep 10.5 at the back of the head and sloping upwardly to the top level of said head at the front thereof, said handle receiving groove supporting the end of said handle between its opposed walls.

2. In combination, a mop having thrums, a 1101 handle, a socket for said handle having a flattened perforated end for pivotal fastening, a mop head comprising a single sheet of metal long in the transverse dimension and short in its front to back dimension, portions of the outer edges of said sheet being perforated and bent downwardly at an angle to the top of said sheet for receiving and holding said thrums, said sheet having a groove midway of the transverse dimension of said sheet, said groove being sufficiently wide to receive the flattened perforated end of said socket and extending substantially the entire distance from the front to the back of said sheet, the groove being deep at the back edge of said head and the bottom thereof sloping upwardly in a straight line to the level of the top of said head at the front thereof, the walls of said groove being perforated adjacent the deepest part thereof, and a pin extending through the perforated end of said socket and the perforations in the walls of the groove when the flattened portion of said socket is in said groove to hold said flattened perforated portion pivotally within said groove, the back edge of said head being shorter than the front edge thereof by an amount equal to the width of material included in the Walls and bot tom of said groove at said back edge.

3. A mop head formed from a single sheet metal blank, said sheet having two substantially flat divergent arms each having the edge portions thereof bend downwards at an angle of ninety degrees and perforated at selected positions, there being a depressed portion between said arms to form a groove therebetween substantially at right angles thereto, said groove being deep and relatively wide at one end and becoming shallow and narrower towards the other end, said latter mentioned end merging into the fiat faces of said arms near the side opposite said deep portion of said groove, the walls of said groove having opposed perforations therein near the deep end thereof, said groove being formed by folding the material of the blank on lines diverging from a point near the side opposite said deep portion of said groove, the back edge of said head being shorter than the front edge thereof by a distance equal to the distance between the outer lines of folding on said back edge.
